DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 700 AM CDT (1200 UTC), the center of Hurricane Katia was located near latitude 21.6 North, longitude 94.6 West. Katia is stationary and little overall motion is anticipated through late today, but the hurricane is forecast to turn southwestward and approach the coast within the watch area late Friday or early Saturday. Maximum sustained winds remain near 80 mph (130 km/h) with higher gusts. Some strengthening is forecast during the next 48 hours and Katia could be near major hurricane strength at landfall. Katia is a small tropical cyclone. hurricane-force winds extend outward up to 10 miles (20 km) from the center and tropical-storm-force winds extend outward up to 70 miles (110 km). The minimum central pressure estimated from Air Force Hurricane Hunter observations is 983 mb (29.03 inches). HAZARDS AFFECTING LAND ---------------------- STORM SURGE: A dangerous storm surge will raise water levels by as much as 5 to 7 feet above normal tide levels near and to the north of where Katia makes landfall. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: Katia is expected to produce total rain accumulations of 5 to 10 inches over northern Veracruz, and 2 to 5 inches over far southern Tamaulipas, northeast Puebla, and southern Veracruz through Saturday morning. Isolated maximum amounts of 15 inches are possible in northern Veracruz. This rainfall may cause life-threatening flash floods and mudslides, especially in areas of mountainous terrain. WIND: Hurricane conditions are expected within portions of the hurricane warning area by late Friday, with tropical storm conditions expected within the tropical warning areas by midday Friday. SURF: Swells generated by Katia are expected to affect portions of the coast of southeastern Mexico today. These swells are likely to cause life-threatening surf and rip current conditions.
